Products
High Purity Series (ASTM elements) and LME Series (additional elements required by London Metal Exchange)
High Purity Series
The High Purity Series consists of eight (8) concentration levels: 0.10 ppm, 0.50 ppm, 1.0 ppm, 3.0 ppm, 5.0 ppm, 10.0 ppm, 20.0 ppm, 50.0 ppm for the following ten (10) analytes. The ten analytes (Ag, As, Bi, Fe, Ni, Pb, Sb, Se, Sn, Te) are required for ASTM Grade I copper cathode certification. Standards are pickled and pre-cut to custom weights between 250 mg and 500 mg according to customer needs.
Set consists of:
100 g CS-001 0.1 ppm
100 g CS-005 0.5 ppm
250 g CS-010 1.0 ppm
100 g CS-030 3.0 ppm
100 g CS-050 5.0 ppm
250 g CS-100 10.0 ppm
100 g CS-200 20.0 ppm
100 g CS-500 50.0 ppm
Purchase of a full set is not required, any concentration may be purchased at a minimum order of 100 grams.
LME Series
The LME Series consists of eight (8) standards at the same concentration levels as the High Purity Series TM.
This series includes five (5) analytes plus gold. These additional analytes are required for LME Grade A copper cathode certification: Co, Cr, Mn, P, Si, +Au. Standards are pickled and pre-cut to custom weights between 250 mg and 500 mg according to customer needs.
Set consists of:
100 g LME-001 0.1 ppm
100 g LME-005 0.5 ppm
250 g LME-010 1.0 ppm
100 g LME-030 3.0 ppm
100 g LME-050 5.0 ppm
250 g LME-100 10.0 ppm
100 g LME-200 20.0 ppm
100 g LME-500 50.0 ppm
Purchase of a full set is not required, any concentration my be purchased at a minimum order of 100 grams.
Copper Certified Reference Material
This copper certified reference material (CS-075) is very useful as a second source standard for verification and as a daily certified check standard. The values in this copper certified reference material are derived from a major U.S. magnet wire manufacturer's material acceptance cut-off levels. It is a good replacement for the BCR ®075 which is now exhausted.
